Description

In this paper we propose a system for painting on surfaces. This system is based on moving charts. At each moment, a local patch is selected on the surface. The patch is formed such that it covers an area on which an artist can easily paint. This patch can be subjected to move in either direction according to the artist's request. For each patch, an optimized 2-D chart is generated and displayed to the user. The user can then paint on this chart. Texture, which is stored in a global atlas is updated due to the user modification. For our application, charts must have as little distortion as possible and chart boundaries should be as smooth and convex as possible. Therefore, we charfity local patches using a low-distortion parameterization while preserving the boundary convexity and smoothness.
